Please pardon the dirty engine. It's been a hell of a few months over here. But, if you must shame me, then go ahead. I'm here for it.
On to the issue: I know the injectors are loud on these babies, but this sounds...extra.
No codes, no misfire. Drives normal. No loss of power or hesitation on acceleration (that I can surmise, anyway). But the timing of the onset of this sound has me curious:
I did my valve cover and spark plugs (OEM motorcraft) last month. Job was fairly straight-forward, other than the fact that I completely stripped the first bolt on the valve cover. I said "fuck it". Got the rest down to spec and figured I'd keep an eye on the oil level/be on the lookout for codes or misfires/check for leaks in the cover.
So far, none of that. Oil dipstick level hasn't budged. Sits right at MAX indicator (although, I have trust issues with this dipstick).
Any thoughts from anyone? Rodney? Injectors? Ecoboom?
